TECHNICAL FIELD

The present disclosure relates to the field of communications systems, and, more particularly, to mobile wireless communications systems and related methods.

BACKGROUND

Cellular communications systems continue to grow in popularity and have become an integral part of both personal and business communications. Cellular telephones allow users to place and receive voice calls most anywhere they travel. Moreover, as cellular telephone technology has increased, so too has the functionality of cellular devices and the different types of devices available to users. For example, many cellular devices now incorporate personal digital assistant (PDA) features such as calendars, address books, task lists, etc. Moreover, such multi-function or “smart” devices may also allow users to wirelessly send and receive electronic mail (email) messages and access the Internet via a cellular network and/or a wireless local area network (WLAN), for example.

Mobile devices such as smart phones are also capable of running relatively sophisticated applications, such as games, document processing applications, chat or instant messaging applications, etc. As a result, it may be desirable to provide enhanced approaches for accessing and managing applications and upgrades thereto for mobile devices, especially as new applications and new versions of existing applications continue to be developed and become available.

The new application portions may be sent to the at least one mobile wireless communications device.

With reference to FIG. 1, a communications system 10 including a mobile wireless communications device 12 according to the present disclosure is now described. Although the communications system 10 is described with reference to one mobile wireless communications device 12, it should be readily understood that there may be any number of mobile wireless communications devices belonging to the communications system.

The communications system 10 includes an application server 18 which comprises a processor 20 and a memory 19 cooperating therewith for storing a plurality of applications. The plurality of applications may include any applications for the mobile wireless communications device 12, for example games, or map applications.

The mobile wireless communications device 12 comprises a processor 16 coupled to a memory 13, a wireless transceiver 14, an input device 15, and a display 17. The memory may be volatile memory, such as RAM, or non-volatile memory, such as flash RAM or a hard drive. The input device 15 may be a keyboard, a thumbwheel, or a trackball, for example. The input device 15 may also be a microphone or a wireless receiver (e.g. bluetooth), as will be appreciated by those of skill in the art. Of course, the display 17 may be a touch sensitive screen and may therefore also serve as the input device 15. In addition, the mobile wireless communications device 12 may include a portable housing and a rechargeable battery.

The processor 16 cooperates with the memory 13 and the wireless transceiver 14 for communicating with an intermediate server 22 via a wireless network 11, that may typically be provided by a cellular telephone network, but any suitable network (for example, WiFi) may be used. The network may be a Code Division Multiple Access (CDMA) network, a 3G network, or other suitable cellular network. Such a cellular network provides for data transfer communications in addition to voice communications, and provides connectivity with the Internet.

The intermediate server 22 comprises a processor 24 cooperating with a memory 25 and a transceiver 23 for communicating with the application server 18. This communication may be via the Internet. The processor 24, and a memory 25 of the intermediate server 22 are also for obtaining respective current version information for associated current versions of the plurality of applications. That is, the intermediate server 22 learns the versions of the applications stored on the application server 18. The intermediate server 22 may obtain this current version information by polling the application server 22, or the application server may send it to the intermediate server without a request therefrom, for example via a server push. Alternatively or additionally, the current version information may be sent to the intermediate server 22 from an outside source (i.e. an administrator).

The processor 24 and memory 25 of the intermediate server 22 further obtain stored user application version information from the mobile wireless communications device 12. That is, the intermediate server 22 learns the version of at least one application stored on the mobile wireless communications device 12. The intermediate server 22 may obtain the stored user application version from the mobile wireless communications device 12 by polling it, or the mobile wireless communications device may send the stored user application version to the intermediate server without a request therefrom, for example via a server push.

The processor 24 and the memory 25 of the intermediate server 22 cooperate to compare the stored user application version with the current version information for the at least one stored user application. If the comparison shows that the stored user application (on the mobile wireless communications device 12) is an older version than the corresponding application stored on the application server 18, the intermediate server 22 downloads, via the transceiver 33, new application portions from the corresponding application stored on the application server 18. Before the intermediate server 22 downloads the new application portions, it compares the application stored on the mobile wireless communications device 12 with the corresponding application stored on the application server 18.

Referring now to FIG. 2A, this comparison is now explained. The application stored on the mobile wireless communications device 12 has portions A, B, and C. The corresponding application stored on the application server 18 is a newer version of the application and includes portions A, B, C, D, and E. The intermediate server 18 downloads application portions D and E, as they are new application portions not included in the version of the application stored on the mobile wireless communications device 12.

After the intermediate server 18 downloads the new application portions, it sends them, via the transceiver 23, to the mobile wireless communications device 12 (which downloads them via its transceiver 14) to thereby update the mobile wireless communications device. The processor 16 and memory 13 of the mobile wireless communications device 12 cooperate to install the new application portions. As shown in FIG. 2B, new application portions D and E have been added to the application stored on the mobile wireless communications device 12 (D and E are shaded to show they have been added).

Another example of the comparing and updating is now described with reference to FIGS. 3A and 3B. In FIG. 3A, the application stored on the mobile wireless communications device 12 has portions A, B, and C. The corresponding application stored on the application server 18 is a newer version of the application and includes application portions A, C, D, E, and F. Thus, application portions D, E, and F are new, while portion B has been removed. The intermediate server 18 downloads application portions D, E, and F as they are the new application portions not included in the version of the application stored on the mobile wireless communications device 12. Further, the intermediate server 22 records that portion B has been removed from the newer version of the application.

The processor 16 and memory 13 of the mobile wireless communications device 12 cooperate to install the new application portions and to remove the application portions no longer contained in the newer version of the application. As shown in FIG. 3B, the new application portions D, E, and F have been added to the application stored on the mobile wireless communications device 12 (D, E, and F are shaded to show they have been added), while application portion B has been removed (indicated with an X).

Those skilled in the art will appreciate that the processor 16 and memory 13 of the mobile wireless communications device 12 may cooperate to install the new application portions based upon user input (approval from the user to install the new application portions) or based upon no user input. In some instances, the mobile wireless communications device 12 may accept user input of which applications may have new application portions installed therefore without user input, and of which applications may have the new application portions installed based upon user input or approval.

In the embodiment schematically illustrated in FIG. 1, the intermediate server 22 updates the mobile wireless communications device by sending the new application portions to the mobile wireless communications device 12 without a request therefrom, for example using a server push. Of course, in other embodiments, the mobile wireless communications device 12 may instead poll the intermediate server 22 for the new application portions.

In addition, in the illustrated embodiment, the mobile wireless communications device 12 selectively sends the stored application version information to the intermediate server 22. The mobile wireless communications device 12 may accept user selection of which stored application version information about which stored user application may be sent to the intermediate server 22. Therefore, the user may advantageously choose which applications he/she would like the intermediate server 22 to update as a matter of course.

In addition to updating applications already stored in the memory 13 of the mobile wireless communications device 12, the intermediate server 22 may send notification of new applications thereto based upon at least one selection preference. The selection preference may be a user selection of an application type, application name, application developer, features supported by an application (i.e. touch screen input, device orientation sensor input from a mobile wireless communications device so equipped, etc), or other suitable selection preference. For example, a user may wish to be notified of any game releases related to a certain movie, or related to a political election.

This functionality of the mobile wireless communications device 12 is now described with additional reference to FIG. 4. Here, the display 17 of the mobile wireless communications device 12 is displaying a list of application categories to the user. The user has selected that he/she would like to receive notification of the availability of new card & casino games, as indicated by the check mark in the box next to that category. This selection preference has been sent from the mobile wireless communications device 12 to the intermediate server 22.

With further reference to FIG. 1, the intermediate server 22 sends notification of availability of at least one new application to the mobile wireless communications device 12 based upon the at least one selection preference, without a request therefrom. For example, this notification may be sent via a server push, but in other embodiments, the mobile wireless communications device 12 may instead query the intermediate server 22 for availability of the at least one new application.

Shown in FIG. 5 is the notification received by the mobile wireless communications device 12 and displayed on the display 17 thereof. Here, the mobile wireless communications device 12 has received and is displaying notification of the availability of ABC Solitaire, XYZ Poker, and QQQ Black Jack. The user may now select at least one of the applications to download and install. The download may be directly from the application server 18 or may instead be from the intermediate server 22. In some applications, the application server 18 or the intermediate server 22 may send the new applications to the mobile wireless communications device 12 without a request therefrom, for example via a server push.

Those skilled in the art will understand that the application server 18 and the intermediate server 22 need not be separate entities. Indeed, such an alternative embodiment of the communications system 10′ is now described with reference to FIG. 7. In this embodiment, the application server 18′ comprises an application module 40′ to store the plurality of applications and an intermediate module 41′. The application module 40′ and the intermediate module 41′ perform the same functions as the application server 18 and intermediate server 22, respectively, as described above. As such, no further description of the application module 40′ and intermediate module 41′ is required, although it should be noted that the application module and intermediate module may comprise computer executable instructions that are stored in the memory 19′ of the application server 18′ and executed by the processor 20′ of the application server.

A method of operating an intermediate server in accordance with the present disclosure is now described with reference to flowchart 30 of FIG. 6. After the start (Block 31), at Block 32, respective current version information is obtained from an application server for associated current versions of a plurality of applications stored thereon. At Block 33, stored application version information is obtained from at least one mobile wireless communications device for at least one application stored thereon.

At Block 34, the stored application version information is compared with the current version information for the at least one stored application. At Block 35, new application portions are downloaded from a current application associated with the current version information. At Block 36, the new application portions are sent to the at least one mobile wireless communications device. Block 37 indicates the end of the method.

Exemplary components of a hand-held mobile wireless communications device 1000 that may be used in accordance with the present disclosure are further described in the example below with reference to FIG. 8. The device 1000 illustratively includes a housing 1200, a keypad 1400 and an output device 1600. The output device shown is a display 1600, which may comprise a full graphic LCD. In some embodiments, display 1600 may comprise a touch-sensitive input and output device. Other types of output devices may alternatively be utilized. A processing device 1800 is contained within the housing 1200 and is coupled between the keypad 1400 and the display 1600. The processing device 1800 controls the operation of the display 1600, as well as the overall operation of the mobile device 1000, in response to actuation of keys on the keypad 1400 by the user. In some embodiments, keypad 1400 may comprise a physical keypad or a virtual keypad (e.g., using a touch-sensitive interface) or both.

The housing 1200 may be elongated vertically, or may take on other sizes and shapes (including clamshell housing structures). The keypad 1400 may include a mode selection key, or other hardware or software for switching between text entry and telephony entry.

In addition to the processing device 1800, other parts of the mobile device 1000 are shown schematically in FIG. 8. These include a communications subsystem 1001; a short-range communications subsystem 1020; the keypad 1400 and the display 1600, along with other input/output devices 1060, 1080, 1100 and 1120; as well as memory devices 1160, 1180 and various other device subsystems 1201. The mobile device 1000 may comprise a two-way RF communications device having voice and data communications capabilities. In addition, the mobile device 1000 may have the capability to communicate with other computer systems via the Internet.

Operating system software executed by the processing device 1800 may be stored in a persistent store, such as the flash memory 1160, but may be stored in other types of memory devices, such as a read only memory (ROM) or similar storage element. In addition, system software, specific device applications, or parts thereof, may be temporarily loaded into a volatile store, such as the random access memory (RAM) 1180. Communications signals received by the mobile device may also be stored in the RAM 1180.

The processing device 1800, in addition to its operating system functions, enables execution of software applications 1300A-1300N on the device 1000. A predetermined set of applications that control basic device operations, such as data and voice communications 1300A and 1300, may be installed on the device 1000 during manufacture. In addition, a personal information manager (PIM) application may be installed during manufacture. The PIM may be capable of organizing and managing data items, such as e-mail, calendar events, voice mails, appointments, and task items. The PIM application may also be capable of sending and receiving data items via a wireless network 1401. The PIM data items may be seamlessly integrated, synchronized and updated via the wireless network 1401 with the device user's corresponding data items stored or associated with a host computer system.

Communication functions, including data and voice communications, are performed through the communications subsystem 1001, and possibly through the short-range communications subsystem. The communications subsystem 1001 includes a receiver 1500, a transmitter 1520, and one or more antennas 1540 and 1560. In addition, the communications subsystem 1001 also includes a processing module, such as a digital signal processor (DSP) 1580, and local oscillators (LOs) 1601. The specific design and implementation of the communications subsystem 1001 is dependent upon the communications network in which the mobile device 1000 is intended to operate. For example, a mobile device 1000 may include a communications subsystem 1001 designed to operate with the Mobitex™, Data TAC™ or General Packet Radio Service (GPRS) mobile data communications networks, and also designed to operate with any of a variety of voice communications networks, such as AMPS, TDMA, CDMA, WCDMA, PCS, GSM, EDGE, etc. Other types of data and voice networks, both separate and integrated, may also be utilized with the mobile device 1000. The mobile device 1000 may also be compliant with other communications standards such as 3GSM, 3G, UMTS, 4G, etc.

Network access requirements vary depending upon the type of communication system. For example, in the Mobitex and DataTAC networks, mobile devices are registered on the network using a unique personal identification number or PIN associated with each device. In GPRS networks, however, network access is associated with a subscriber or user of a device. A GPRS device therefore utilizes a subscriber identity module, commonly referred to as a SIM card, in order to operate on a GPRS network.

When required network registration or activation procedures have been completed, the mobile device 1000 may send and receive communications signals over the communication network 1401. Signals received from the communications network 1401 by the antenna 1540 are routed to the receiver 1500, which provides for signal amplification, frequency down conversion, filtering, channel selection, etc., and may also provide analog to digital conversion. Analog-to-digital conversion of the received signal allows the DSP 1580 to perform more complex communications functions, such as demodulation and decoding. In a similar manner, signals to be transmitted to the network 1401 are processed (e.g. modulated and encoded) by the DSP 1590 and are then provided to the transmitter 1520 for digital to analog conversion, frequency up conversion, filtering, amplification and transmission to the communication network 1401 (or networks) via the antenna 1560.

In addition to processing communications signals, the DSP 1580 provides for control of the receiver 1500 and the transmitter 1520. For example, gains applied to communications signals in the receiver 1500 and transmitter 1520 may be adaptively controlled through automatic gain control algorithms implemented in the DSP 1580.

In a data communications mode, a received signal, such as a text message or web page download, is processed by the communications subsystem 1001 and is input to the processing device 1800. The received signal is then further processed by the processing device 1900 for an output to the display 1600, or alternatively to some other auxiliary I/O device 1060. A device user may also compose data items, such as e-mail messages, using the keypad 1400 and/or some other auxiliary I/O device 1060, such as a touchpad, a rocker switch, a thumb-wheel, track ball, or some other type of input device. The composed data items may then be transmitted over the communications network 1401 via the communications subsystem 1001.

In a voice communications mode, overall operation of the device is substantially similar to the data communications mode, except that received signals are output to a speaker 1100, and signals for transmission are generated by a microphone 1120. Alternative voice or audio I/O subsystems, such as a voice message recording subsystem, may also be implemented on the device 1000. In addition, the display 1600 may also be utilized in voice communications mode, for example to display the identity of a calling party, the duration of a voice call, or other voice call related information.

The short-range communications subsystem enables communication between the mobile device 1000 and other proximate systems or devices, which need not necessarily be similar devices. For example, the short-range communications subsystem may include an infrared device and associated circuits and components, or a Bluetooth™ communications module to provide for communication with similarly-enabled systems and devices
